Finish a single leg by rolling?

It's a little hard to describe, but has anyone seen someone finish a single leg by holding onto the leg and rolling sideways, underneath the leg being held? Kind of forcing your opponent to roll with you because of the pressure on the knee?

I think I first saw this in pro wrestling (I know, I know), but when I began to study real grappling, I found a lot of the moves in pro wrestling came from real wrestling. Just wondering if anyone has seen this finish to a single leg and if it's effective or not.

^Exactly^ Never heard the term leg whizzer, but seems like a pretty good description. Any comments on its effectiveness, or videos of the move? Is it worth finishing a single like that? Seems like it would work best in a "surprise! If you don't go with me, you'll never train jiu-jitsu again!" kind of way.

BTW for those who are reading I'm serious. I realize I could be nicer about it but when posting here if all you're going to do is argue about what you're supposed to call it stay out of this section of the forum. I don't care if you think it's casual conversation. The issues discussed in this part of the forum are about advanced techniques and how they work. The only discussion about what it is called should only be brought if nobody knows what it is. If we don't lay down this rule then you're going to be having the Judoka, Catch, and BJJ'ers arguing forever.

Name aside, there are several ways to perform that particular finish: barrel roll to the inside, rotate the person around you, lift the leg on your shoulder and perform a forward roll, etc. It does work but you have to have the timing down and, like Omega said, your opponent has to be giving you the right momentum.
